>There are several ways to approach this. The simplest
way is to use GdkRGB, see gdk/gdkrgb.h. You create an RGB
buffer, render to your RGB buffer, then use GdkRGB routines to
copy your RGB buffer to a drawing area or custom widget. The
book "GTK+/Gnome Application Development" gives some details;
GdkRGB is also documented in the GTK+ reference
documentation.</P

>If you're writing a game or other graphics-intensive
application, you might consider a more elaborate
solution. OpenGL is the graphics standard that will let you
access hardware accelaration in future versions of XFree86; so
for maximum speed, you probably want to use OpenGL. A
GtkGLArea widget is available for using OpenGL with GTK+ (but
GtkGLArea does not come with GTK+ itself). There are also
several open source game libraries, such as ClanLib and Loki's
Simple DirectMedia Layer library (SDL).</P
